Hello,
I want to code an android application which can communicate with whatsapp servers and do following things from within the software:
1. Ask for user's mobile number and submit that number to whatsapp servers for notification
2. Complete the SMS verification process by submitting verification code back to whatsapp servers
3. Get list of all groups and contacts
4. Ability to send messages to groups/contacts
Whatsapp Do not provide an official API to integrate its services to an android application.
You can use some of the already available unofficial open-source API to understand how whatsapp servers are being communicated.
Some references to study how whatsapp server communicates with its clients:
Unofficial PHP library: [login to view URL] [ this one is currently not fully functioning ]
Research paper which talks about Decrypting and understanding the WhatsApp architecture

Whatsapp is known to communicate via FunXMPP protocol, so you might need to intercept TCP level traffic and study messages being sent via this protocol to fully create this application.
